Context. We use optical photometric and polarimetric data of BL Lacertae that cover a period of 22 years to study the variability of the source.
Aims. The long-term observations are employed for establishing parameters of a stochastic
model consisting of the radiation from a steady polarized source and a number of
variable components with different polarization parameters, proposed by the authors early.
Methods. We infer parameters of the model from the observations using numerical simulations based
on a Monte Carlo method, with values of each model parameter selected from a Gaussian distribution.
We determine the best set of model parameters by comparing model distributions to the observational ones using the χ2 criterion.
Results. We show that the observed photometric and polarimetric variability can be explained within a model
with a steady source of high polarization, ~40%, and with direction of polarization
parallel to the parsec scale jet, along with 10±5 sources of variable polarization
